A curious bit of C# code - needs some explaining

Why use try {} finally {} with an empty try block?

While stepping through MS .NET code I have stumbled upon this piece:

try { } finally 
{
  // Called in a finally because it needs to run uninterrupted in order to maintain consistency.
  queued = IOThreadScheduler.current.ScheduleCallbackHelper(callback, state);
}

Interesting trick. Can anyone one donate an explanation?

Answer 1

This is most likely intended to execute the line in the presence of a ThreadAbortException.

According to the docs:

When this exception is raised, the runtime executes all the finally blocks before ending the thread.
